Some characteristics of the diffusion of carbon in molybdenum carbide

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Summary

  1. 1.

    The effects of temperature on the coefficients of self-diffusion and heterodiffusion of carbon in molybdenum carbide have been determined.

  2. 2.

    The coefficients of heterodiffusion at the temperatures investigated are some two orders of magnitude greater than the coefficients of self-diffusion.

  3. 3.

    The difference between the coefficients of diffusion may be attributed to the strong dependence of thermodynamic activity on the concentration of carbon in molybdenum carbide.
